132 Knowing Performance and Safety Guidelines
Getting the Most Out of Your Reception
Keeping Tabs on Signal Strength
The quality of each call you make or receive depends on the signal strength in your
area. Your phone informs you of the current strength by displaying a number of bars
next to the signal strength icon. The more bars displayed, the stronger the signal. If
you’re inside a building, being near a window may give you better reception.
Understanding Power Save Feature
If your phone is unable to find a signal after 15 minutes of searching, a Power Save
feature is automatically activated. If your phone is on, it periodically rechecks service
availability or you can check yourself by pressing any key. Anytime the Power Save
feature is activated, a message displays on the screen. When a signal is found, your
phone returns to Standby mode.
Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it’s turned on, it
receives and transmits radio frequency (RF) signals. When you use your phone, the
system handling your call controls the power level. This power can range from 0.006
watts to 0.2 watts in digital mode.
Knowing Radio Frequency Safety
The design of your Sprint PCS Phone complies with updated NCRP standards
described below.
In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE) and the
American National Standards Institute (ANSI) joined in updating ANSI’s 1982
standard for safety levels with respect to human exposure to RF signals. More than
120 scientists, engineers and physicians from universities, government health
agencies and industries developed this updated standard after reviewing the available
body of research. In 1993, the Federal Communications Commission (FCC) adopted
this updated standard in a regulation. In August 1996, the FCC adopted hybrid
standard consisting of the existing ANSI/IEEE standard and the guidelines published
by the National Council of Radiation Protection and Measurements (NCRP).
Maintaining Your Phone’s Peak Performance
There are several simple guidelines to operating your phone properly and
maintaining safe, satisfactory service.
ᮣ Hold the phone with the antenna up, fully-extended and over your shoulder.
ᮣ Try not to ever hold, bend or twist the phone antenna.
ᮣ Don’t use the phone if the antenna is damaged.
ᮣ Speak directly into the mouthpiece.
